Pro tennis players

Is he known for that?
I think it was well cited in his early days he was a bit of a player (believe he's said this in multiple interviews now that he's a little older and wiser) hence Nick's off hand comment to Stan. Not sure if we ever actually got confirmation that he slept with her (Vekic?) or anyones GF for that matter; however, I do seem to remember the GF gave a statement and basically said how disappointing Nick's comments were but never defended herself or said he was wrong. I guess take that as you will.
